Ignore prefix created if same vlue already existed on Netbox

I have fixed all prefix duplicate issue after remove those duplicated prefix in mgmt vrf, after re-discovery, Netdoc auto re-create those prefix

Prefixes are created based on IP VRF. Can you double check if duplicated prefixes have different VRFs?

Yes it is different vrf.

When discover mgmt switch, the mgmt IP is belong to mgmt-vrf, then it keep re-create mgmt-vrf

Ok, the procedure is: Update IP address and prefix, setting the right VRF Delete useless prefixes Check in the report if everything is fine Import from ARP table Check Wiki for additional details.

Hi @dainok ,

I have followed the procedure correctly, the point is when running discovery script periodically , netdoc will import the deleted VRF again

Check #111
